DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.

FIG. 1 is a schematic perspective view of a front side of a digital camera 10 as an example of an image processing apparatus, according to an embodiment of the invention. FIG. 2 schematically illustrates a back side of the digital camera 10 according to another embodiment of the invention.

Referring to FIGS. 1 and 2, the digital camera 10 includes a body 10 a and a lens module 100.

The body 10 a may be a body of the digital camera 10 and may include various types of components necessary for operating the digital camera 10 including an image capturing such as a charge-coupled device or a complementary metal oxide semiconductor (CMOS) via which an image is input.

The lens module 100 is installed on the body 10 a. Here, the lens module 100 may be an interchangeable lens module that is detachably installed on the body 10 a. However, embodiments of the invention are not limited thereto, and thus the lens module 100 may be a fixed lens module and not the interchangeable lens module.

The lens module 100 includes a lens barrel 100 a and a control ring 110. The lens barrel 100 a includes one or more lenses which are installed to move relatively along an optical axis. The control ring 110 is controlled to change a setting value.

Accordingly, the digital camera 10 according to embodiments may allow the lens module 100 to set a setting value which is to be set by the body 10 a. Thus, the digital camera 10 may be further conveniently set for capturing or other various operations.

Setting values of several setting items may be set or changed for capturing or other various operations performed by the digital camera 10. Here, if the control ring 110 is adjusted, setting values of a designated setting item may be set or changed.

A setting item set under the control of the control ring 110 may be at least one of a photographing mode, a white balance, an exposure correction, a color correction, a flash light control, a sensitivity control, a digital zoom, and a focus area change.

If a zoom magnifying power of the digital zoom is selected to be changed under the control of the control ring 110, a short focus lens may also change a view angle using a digital zoom.

The digital camera 10 further includes a selector, which may be configured to allow selection of a setting item so that the control ring 110 sets a setting value for the setting item. In other words, a setting item to be controlled by the control ring 110 may be changed by the selection operation of the selector. For example, setting items which can be set may be designated, an order of the setting items may be designated, and a setting item set by the control ring 110 may be changed according to the number of times selected by the selector under the control of the control ring 110.

Here, the selector may be installed on the lens module 100 or the body 10 a. According to an embodiment of the invention, the selector may be a changeover switch (120 of FIG. 1) or a changeover button (420 of FIG. 4), which is installed to be exposed outside the lens module 100. Here, the changeover switch may be a sliding type switch.

According to another embodiment of the invention, the selector may be a sliding switch such as a changeover switch (120 of FIG. 1) or a rotation changeover switch such as a button (20 of FIG. 2) or a mode dial (13 of FIG. 1) which is installed on the body 10 a. According to another embodiment of the invention, the selector may be a menu system that is displayed on a display apparatus 15, which is installed on the body 10.

One of the changeover switch 120, the changeover button 420, the mode dial 13, and the menu system displayed on the display apparatus 15 may be used as the selector 120. Alternatively, two or more of the changeover switch 120, the changeover button 420, the mode dial 13, and the menu system displayed on the display apparatus 15 may be simultaneously used as the selector 120.

The control ring 110 is installed on and encloses at least a part of an outer surface of the lens barrel 100 a or the outer surface of the lens barrel 100 a. Here, the control ring 110 may be installed on and rotate on the lens barrel 100 a. In this case, the control ring 110 may be controlled to rotate on the lens barrel 100 a. Here, the control ring 110 may have a structure capable of rotating a predetermined section or amount.

According to another embodiment of the invention, the control ring 110 may be installed on the lens barrel 100 a to slide along the lens barrel 100 a, which may be sliding along an optical axis of the lenses. In the embodiment, the control ring 110 may slide back and forth on the lens barrel 100 a along the optical axis.

Embodiments of the invention are not limited thereto, and thus the control ring 110 may be installed to rotate and slide on the lens barrel 100 a. In this case, the control ring 110 may be controlled to rotate and/or slide on the lens barrel 100 a. As described above, the control ring 110 may operate in various forms to improve convenience to a user when a setting value is set by the control ring 110.

The control ring 110 may slide to select a setting item which is to be set and/or may rotate to change a setting value of the setting item.

According to another embodiment of the invention, as shown in FIG. 8, the selector 120 may be a selection ring 820 which is installed to rotate and/or slide on a lens barrel 800 a. In this case, the selection ring 820 may be controlled to select a setting item which is to be set. Also, the selection ring 820 may be configured so that one of the control rings controls the setting value of the setting item.

According to an embodiment of the invention, the selector, e.g., the selection ring 820, may slide to select at least one of other control rings and may rotate to set a setting item which is to be set and control the control ring in order to set a setting value of the setting item.

Besides the lens module 100 illustrated in FIG. 1, various types of lens modules as shown in FIGS. 3 and 4 may be interchangeably installed on the digital camera 10.

The lens module 100 illustrated in FIG. 1 includes one control ring 110. The control ring 110 may be at least one of a focus control ring which controls a focus, a zoom control ring which controls a zoom, and an aperture control ring which controls an aperture.

The lens module 100 may include at least one of the focus control ring, the zoom control ring, and the aperture control ring, and the selector may select at least one of the focus control ring, the zoom control ring, and the aperture control ring as the setting item for the control ring 110 to control. In this case, a setting value to be set may be easily set or changed without installing an additional device and an additional sensor structure for an additional control ring.

The control ring 110 may pre-designate a setting item, and the selector 120 may indicate which of the setting items, a focus, a zoom, or an aperture, will be controlled by the control ring 110.

A lens module 300 illustrated in FIG. 3 includes a control ring 310, a focus control ring 350, and a zoom control ring 360 which are installed on a lens barrel 300 a. In other words, the control ring 310 may be separately installed along with the focus control ring 350 and the zoom control ring 360.

The control ring 310 of FIG. 3 may perform the same function as that of the control ring 110 of FIG. 1. In this case, an additional selector may not be installed on the lens module 300 but may be installed only on the body 10 a.

A lens module 400 illustrated in FIG. 4 includes a focus control ring 450, a zoom control ring 460, and an aperture control ring 470 which are installed on a lens barrel 400 a. Here, a changeover button 420 may be further installed on the lens barrel 400 a as a selector 420.

The changeover button 420 may select one of the focus control ring 450, the zoom control ring 460, and the aperture control ring 470 so that the selected one performs the same function as that of the control ring 110 of FIG. 1. In the embodiment illustrated in FIG. 4, the selector selects the focus control ring 450 so that the focus control ring 450 performs the function of the control ring 110 of FIG. 1.

Here, a push button may be used as the changeover button 420, which is the selector. In this case, as shown in FIG. 5, the selector may not protrude substantially outside the lens module 400 but may be exposed outside the lens module 400. Thus, the selector may be prevented from malfunctioning due to a user's unintentional pressing of the changeover button 420 of the selector.

The shutter-release button 12, the mode dial 13, and the like are installed on an outer surface of the body 10 a of the digital camera 10. A direction button 16, a menu-OK button 17, the display panel 15, and the like are installed on the backside of the digital camera 10.

The shutter-release button 12 is used to open and/or close a shutter in order to expose the image capturing device (e.g., the CCD or the CMOS) to light for a predetermined time. A selection of a photographing mode may be input through the mode dial 13.

Various modes including an auto (photographing) mode, a scene mode, an effect mode, an A/S/M mode, and the like may be selected and input at the body 10 a of the digital camera 10. Here, the auto mode is used to minimize user's settings through the dial mode 13 and rapidly and conveniently capture an image according to a use purpose. The scene mode is used to simply set an optimal state of the digital camera 10 according to photographing situations or a state of a subject. The effect mode is used to a specific effect such as continuous photographing, scene photographing, or the like, to image capturing. The A/S/M mode is used to manually set various functions including aperture and shutter speeds and the like in order to capture an image.

The modes may further include an additional mode in which at least one of the focus control ring, the zoom control ring, and the aperture control ring of the lens module 100 functions as the control ring 110, e.g., an intelligent function mode. In this case, the mode dial 13 may further include the intelligent function mode, and if the intelligent function mode is selected, a set control ring may operate as the control ring 110.

The direction button 16 includes four buttons, i.e., up, down, left, and right buttons. Various menus of operations of an image processing apparatus such as a digital camera may be executed through operations of the direction button 16 and the menu-OK button 17 to be displayed on the display panel 15.

Here, a menu system may be displayed on the display apparatus such as the display panel 15 and may operate through manipulations of a touch screen and/or the direction button 16 and the menu-OK button 17. In this case, the menu system may control the control ring 110 to designate setting items which can be set and an order of the setting items.

The menu system may be a selector according to an embodiment of the invention or may be the selector, which changes a setting item to be set.

A control switch 11 is installed on the body 10 a of the digital camera 10 to transfer a lens back and forth. Here, the control switch 11 includes a front control switch 11 a and a rear control switch 11 b.

The front control switch 110 may operate the lens module 100 to transfer the lens forward. The rear control switch 110 b may operate the lens module 100 to transfer the lens backward.

In the embodiment illustrated in FIG. 1, the focus control ring may be used as the control ring 110. In this embodiment, the selector may select the control ring 110 so that the control ring 110 functions as the focus control ring or a control ring for setting a setting value of a designated setting item.

If the control ring 110 is used as the focus control ring, the control ring 110 may be controlled to transfer a focus lens installed in a lens barrel forward or backward along the optical axis in order to control a focus.

In particular, since the focus control ring is not used in an auto focus mode, the focus control ring may be automatically used as the control ring 110, without a selection operation of the selector 120 in the auto focus mode. In this case, the focus control ring may be set to control the focus in a manual focusing mode.

FIG. 6 is a block diagram of an image processing apparatus 200 according to an embodiment of the invention. FIG. 7 is a diagram illustrating a signal flow in the image processing apparatus 200 including a control ring 610, according to an embodiment of the invention.

Referring to FIGS. 6 and 7, an optical system (OPS) includes a lens unit and a filter unit and optically processes light incident from a subject. The lens unit of the OPS includes a zoom lens, a focus lens, and a compensation lens.

A microcontroller 212 controls a lens driver 210 to drive a zoom motor “M_(Z)” in order to move the zoom lens. In embodiments, if a wide angle-zoom button is pressed, a focal length of the zoom lens is shortened to widen a view angle. If a telephoto-zoom button is pressed, the focal length of the zoom lens is lengthened to narrow the view angle.

If a zoom control ring 250 is controlled, a zoom control ring position signal “S2” is input to a controller 230, and the controller 230 outputs a zoom driving signal “C2” to the zoom motor “M_(Z)” in order to drive the zoom motor “M_(Z),” thereby controlling a position of the zoom lens. Here, the controller 230 may be the microcontroller 212 and/or a digital signal processor (DSP) 207 of FIG. 6.

In an auto focus mode, a main controller of the DSP 207 controls the lens driver 210 through the microcontroller 212 to drive a focus motor “M_(F).” The main controller may drive a focus motor “M_(F)” to move the focus lens to a focus position in which the clearest picture can be obtained, in order to perform an automatic focus control.

In embodiments, if a focus control ring 240 is controlled, a focus control ring position signal “S1” is input to the controller 230, and the controller 230 outputs a focus driving signal “C1” to the focus motor “M_(F)” to drive the focus motor “M_(F)” in order to control a position of the focus lens.

The compensation lens compensates for a whole refractive index and thus in embodiments is not separately driven. Reference character “M_(A)” denotes an aperture control motor for driving an aperture (not shown).

Here, if an aperture control ring 260 is controlled, an aperture control ring position signal “S3” is input to the controller 230, and the controller 230 outputs an aperture driving signal “C3” to the aperture control motor “M_(A)” to drive the aperture control motor “M_(A)” in order to control the aperture.

An optical low pass filter (OLPF) of the filter unit of the OPS removes optical noise of a high frequency component. An infrared cut filter cuts an infrared component of incident light.

An optoelectric converter (OEC) may include an imaging device such as a CCD, a CMOS, or the like. The OEC converts the light incident from the OPS into an electric analog signal.

An analog-to-digital converter (ADC) includes a correlation double sampler and analog-to-digital converter (CDS-ADC) 201. The ADC processes the electric analog signal output from the OEC to remove high frequency noise and control amplitude and converts the electric analog signal into a digital signal. Here, the DSP 207 controls a timing circuit 202 to control operations of the OEC and the ADC.

A real-time clock (RTC) 203 provides time information to the DSP 207. The DSP 207 processes the digital signal output from the CDS-ADC 201 to generate a digital image signal, which is classified into a luminance signal (a Y value) and a chromaticity (R, G, and B) signal.

A lamp unit “LAMP” is driven by the microcontroller 212 under the control of the main controller of the DSP 207. The lamp unit “LAMP” includes a self-timer lamp, an auto-focus lamp, a mode instruction lamp, a flash standby lamp, and the like. A user input unit “INP” includes the direction button 16, the menu-OK button 17, the shutter-release button 12, and the like.

A dynamic random access memory (DRAM) 204 temporarily stores the digital image signal output from the DSP 207. An electrically erasable and programmable read only memory (EEPROM) 205 stores a booting program necessary for an operation of the DSP 207, an algorithm such as a key input program or the like, and setting data. A memory card is interchangeably installed in a memory card interface (MCI) 206.

The digital image signal output from the DSP 207 is input to a display panel driver 214, and thus an image is displayed on a display panel 215.

The digital image signal output from the DSP 207 may be transmitted in series through a universal serial bus (USB) connector 31 a or an RS232C interface (I/F) 208 and an RS232C I/F connector 31 b or may be transmitted as a video signal through a video filter 209 and a video output unit 31 c. Here, the DSP 207 may include a microcontroller.

An audio processor 213 outputs an audio signal input from a microphone “MIC” to the DSP 27 or a speaker “SP” and outputs an audio signal input from the DSP 207 to the speaker “SP.”

The image processing apparatus 200 according to embodiments include the control ring 610, a selector 620, and the controller 230. The control ring 610 and the selector 620 may be installed on a lens module 700.

The control ring 610 may be installed to enclose at least a part of an outer surface of a lens barrel 700 a. The controller 230 receives control ring position information “S4” of the control ring 610 and sets a setting value according to the control ring position information “S4” of the control ring 610.

The selector 620 generates a change signal through a selection operation thereof. In this case, the controller 230 receives the change signal and changes a position of the control ring 610 to set a setting value of another setting item according to the position of the control ring 610.

Here, the control ring 610 corresponds to the control ring 110 of FIG. 1, and the selector 620 corresponds to the selector such as the changeover switch 120 of FIG. 1. Therefore, the control ring 610 and the selector 620 according to embodiments perform the same functions as those of the control ring 110 and the selector such as the changeover switch 120 of FIG. 1, respectively.

The image processing apparatus 200 further includes a display which displays a menu system. Here, the display includes the display panel driver 214 and the display panel 215. In this case, the menu system may change a position of the control ring 610 to set another setting value according to the position of the control ring 610.

If the control ring 610 is controlled, control ring position information “S4” is input to the controller 230, and the controller 230 sets a setting value of a designated setting item according to the control ring position information “S4.”

A control ring installed on an interchangeable lens may be controlled to set a setting value necessary for capturing or other operations in order to improve convenience to a user.

The control ring position information “S4” may be obtained by at least one of various sensors including a plurality of brushes, a plurality of patterns, a photo interrupt sensor, and a potentiometer.

FIG. 8 is a diagram of the image processing apparatus 200 of FIG. 6, including the selection ring 820, according to another embodiment. The image processing apparatus 200 according to embodiments include control rings 240, 250, and 260, the selection ring 820, and the controller 230. Here, the control rings 240, 250, and 260 and the selection ring 820 are installed on a lens module 800.

The control rings 240, 250, and 260 may be installed to enclose at least a part of an outer surface of the lens barrel 800 a. Here, the control rings 240, 250, and 260 may include a focus control ring 240, a zoom control ring 250, and an aperture control ring 260, respectively. At least one of the control rings 240, 250, and 260 may be a control ring according to embodiments of the invention.

The selection ring 820 may select at least one of the focus control ring 240, the zoom control ring 250, and the aperture control ring 260 as a control ring or may set a setting item to be set. The controller 230 receives control ring position information “S8” of the selection ring 820 and selects at least one of the control rings 240, 250, and 260 as a control ring or sets a setting item to be set according to the position information “S8” of the selection ring 820.

The selection ring 820 may generate a change signal through a selection operation thereof. The controller 230 receives the change signal to change a position of a control ring in order to set a setting value of another setting item according to the position of the control ring.

In embodiments, the control ring corresponds to the control ring 110 of FIG. 1, and the selection ring 820 corresponds to the selector 120 of FIG. 1. Therefore, the control ring and the selection ring 820 according to embodiments perform the same functions as those of the control ring 110 and the selector 120 of FIG. 1, respectively.

In other words, a selector may be the selection ring 820 which is installed on the lens barrel 800 a to rotate and/or slide on the lens barrel 800 a. In this case, the selection ring 820 may set a setting item to be set. Also, the selection ring 820 may select one of other control rings as a control ring which controls a setting value of the setting item.

According to embodiments of the invention, a selector, e.g., the selection ring 820, may slide to select at least one of other control rings and may rotate to set a setting item to be set and control the control ring in order to set a setting value of the setting item.

The image processing apparatus 200 may control the control ring 610 to control focus areas 91 and 92 (see FIG. 9). FIG. 9 schematically illustrates a screen for controlling the focus areas 91 and 92 under control of the control ring 610. The screen illustrated in FIG. 9 may be a screen displayed on the display panel 214 of the display. Arrows in FIG. 9 denote paths through which the focus areas 91 and 92 move under the control of the control ring 610.

The display may display an image and an area of the image as the focus areas 91 and 92. Here, the focus areas 91 and 92 may be rotated and changed in a set direction under the control of the control ring 610.

If the control ring 610 is rotated to the left, the focus areas 91 and 92 may be rotated and moved to the left on the screen. If the control ring 610 is rotated to the right, the focus areas 91 and 92 may be rotated and moved to the right on the screen. Here, a rotation direction of the control ring 610 and rotation directions of the focus areas 91 and 92 may be set to opposite directions.

According to another embodiment, the control ring 610 may rotate in a set direction in the image to move from the focus area 91 positioned in an outer area to the focus area 92 positioned in a central area according to a control direction of the control ring 610. The control ring 610 may rotate in the set direction in the image to move from the focus area 91 to the focus area 92 according to the control direction of the control ring 610.

Here, if the control ring 610 is rotated to the left, the focus areas 91 and 92 may be rotated to the left of the image on the screen and the control ring 610 may move from the focus area 91 to the focus area 92. If the control ring 610 is rotated to the right, the focus areas 91 and 92 may be rotated to the right of the image and the control ring 610 may move from the focus area 92 to the focus area 91.

Accordingly, the control ring 610 may be controlled to easily move the focus areas 91 and 92 and to improve user convenience when setting focus areas.
